That is the worst advice I have read in a while, and coming as your first post I find it strange you would offer advice at all? Spending money on juice isn't going to help when they are looking for a PV? They want to UPGRADE. A cheap chinese battery is comparable to any other would be correct. However, what this person needs is NOT ANOTHER cheap chinese disposable battery. This person needs to get a set up that will SAVE money over the long run with LESS hassle.
As a few posters before me mentioned, you can get a decent PV for less than $60 which is a better regulated battery HOLDER. You buy the battery and charge it outside the unit so you only need to swap out batteries instead of charging the whole thing. The batteries last over a year (versus ~250 charges for the eGo) and are about $10 each. VV Gripper is one, a simple box mod is one, there are several tube styles also (Bolt, Lavatube etc.) and on the upside is the Provari.
There are coupon codes here for a lot of vendors, and with the holidays coming up I am sure they will be having some great sales. After you find the unit you want, do a search for "coupon codes" for that vendor and if they don't have a sale / coupon, find a vendor that does. Most vendors will offer discounts you just have to find them, a common code is ECF10 for ECF members to save 10% off every order. If it isn't on sale or with a coupon code, I don't buy it because I know the minute I do the vendor will have a sale
Best of luck, and congrats on giving up the cigarettes.
